At a glance

KASSON TAP 1 is a 115 kV electric substation in California, recorded in the HIFLD transmission dataset. 3 transmission lines connect to it. 428 of California's 3,003 named substations operate in a higher voltage band. The highest-scoring datacenter candidate site within about 25 miles is TESLA Power Project in Alameda County, with a DC Readiness score of 67/100.

KASSON TAP 1 is an electric transmission substation in California. It is classified as sub-transmission (115 kv) and connects 3 transmission lines. Substation proximity is one of the strongest speed-to-power signals for siting a datacenter — interconnection distance to an energized, high-voltage bus is often the binding constraint on time-to-energization.
